FILING-APPLIANCE CASE.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed December 31, 1914. Serial No. 879,962.

United States, residing at Alliance, county of Stark, and State of Ohio, have invented:

certain new and useful Improvements in Filing-Appliance Cases, of which the fol lowing is a s ecification.

The invention relates to a case for a filing appliance or the like, which may include a series of hinged holders operatively mounted therein and adapted to be completely in: closed by the case'for protection against fire and like damage.

The invention may be embodied in a. case having a rectangular base composed of a lower or base section, and an upper or cover section, with uiding hinge connections between the sections, so that the upper section can be closed downward upon the base sex:- tion to completely incase the bill holders mounted therein, or can be swung upward with its rear end resting upon the rear portion of the base section to form a back or support for the bill holders in operative position.

The upper and lower sections of cases of this character havebeen made of spaced sheet metal face plates or walls with intervening heat resisting material, with metal bars secured between the rims of the walls, or sheet metal frames telescoped over the same; but such rim bars or frames conduct so much heat that the contents of the case or cabinet cannot be properly preserved and protected from external heat.

The object of the present improvement is to construct the body and rims of cases or cabinets of this character 1n such a manner that there is no continuous metal contact between the outer and inner metal face plates may be arranged to abut corresponding flanges on the rim of the opposing case or cabinet section; thereby providing a metal contact between the outer and inner ortions of opposing rims, without any meta lie contact or connection between the outer and inner walls or flanges of the res ective rims. The invention ma be embo ied and its ObJBCiZS attained in t e construction and arrangement illustrated in the accompanying drawings, formin part thereof, in which- Figure 1 is a side elevation of a filing appllance case containing the improved rim construction;

Fig. 2, a longitudinal section of the same; Fig. 3, a fragmentary plan view of one corner of the base section of the case, with parts broken away to show details of the rim construction; Fig. 4, a section on line 44, Fig. 3; Fig. 5, a section on line 5- 5, Fig. 3; Fig. 6, a section showing two opposing rims closed together with portions of the heat resisting material omitted to show details of construction, and

Fig. 7, a detached view of one abutment chair or bracket.

Similar numerals refer to similar parts throughout the drawings.

The case may be composed of the substantially similar rectangular base or bottom section 1, and the cover or top section 2, which are operatively connected together by means of the guiding hinge brackets 3, one being located on each side of the rear end portion of the case. 'A series of bill holders tmay be hinged to other attheir rear ends, and one of the holders me. have its hinged end pivoted to the rear en rim of the cover section. V

An index frame 5 may be pivoted at its rear end to the hinged end of the lower frame, and may have its forward end supported by guiding means 6 for directing it forward and rearward out of and into the case. counterbalance means 7 ma also be rovided for the case sections am? the bill olders, but these devices do not form any part of the present invention and need not be described in detail.

Each case section is preferabl made of an outer and inner sheet metal ace plate or wall 8 and 8'; which walls are pressed or otherwise formed to the rectangular shape of the case section, and the outer wall 8 is made enough larger than the inner wall 8',

. ture 17 for receivin )oints to form an intervening cavity which s filled with a heat resisting material 9 to form a fire proof structure.

The rims of the walls 8.and 8 may be connected together by means of the intervening rim bar 10 composed of heat resisting or insulating material which is preferably made .of transite asbestos wood, or other like substance. When it is desired to provide one or more metal contact faces, for the abutting edges of the rims of separable case sections, the L-shaped rim frames or flanges 11 are provided on one or bothsides of the rim bar 10, which frames have their wider outer flange 12 integral wit'h'or secured by brazing or riveting to the outer sides of the wall rims; and preferably have their narrower inner flanges 13 inclined or beveled inward, so that the free edges only thereof will contact with the heat resisting rim bar. The metal walls and rim flanges may be.

secured to the intervening rim bar 'by means of the rivets 14 or the screws 15, and suitable abutment chairs 16 of the same de th as the rim flanges, are preferably provi ed between each metal wall and the rim bar,-

to properl space the same apart; one chair being us for each rivet or screw, and each chair being provided with the central aperthe shankof the same.

In the preferre form. of construction illustrated in the drawings, rivets 14 are used for securing the outer metal wall to the rim bar, and a washer 18 is used on the inner end of each rivet. A shown in the drawings, these rivets do not extend inward far enough to contact with the inner metal wall, and the interval between the inner head i of the. rivet and the inner wallis filled with the heat resisting material 9. And in the same form of construction, the inner metal wall is secured to the'rim' bar means of the screws 15 which pass throug into, but not beyond the rim bar. The securin rivets and screws are staggered or s ac apart along the rimso that neither t e rivets or screws, nor the abutment. chairs, will contact with each other; and the abutment chairs are also so proportioned that they will not contact with any portion of the rim flanges. a

The preferred method of assembling the parts is b securing the rim barto the outer metal wal and rim flange by means of the rivets 14, and then inserting the inner metal wall and rim flange into proper position inside the rim bar and securing these parts together by means of the screws 15, by which arrangement of the parts the heads of rivets only are exposed on the outer side of the case or cabinet; after .which the heat resisting material 9 may be inserted between the metal walls, as for instance, by injecting it in a liquid or powdered form through an 'pinge the correspondin aperture inone of the walls, and thenplugglng or otherwise closing the aperture.

By this construction and arrangement. it is evident that a strong and substantial rim is provided for connecting the s1 ced edges of the metal walls, which rim also serves to close the spaced interval between the edges and forms a completely closed cavity between the metal walls for the reception of the heat resisting material. And it is furthermore evident that there is no continuous metal connection or contact between the outer and inner walls for conducting heat from one wall to the other.

As shown in Fig. 6, the rim faces of the L-shaped flanges may be arranged to imfaces of an oppos mg rim, thereby providing a metallic contact to receive the pressure and wear of the clamping means, as for lnstance, the locking bolt 19, conventionally shown in Fig. 2.

The triangular space \between the inclined inner portion of each L-flange which is ad jacont to the side of the rim bar, may be filled by suitable heat resistin material; and it is evident that the inclination. of these flanges which extendbeyond the edge of the rim bar, avoids a rubbing contact with the correspondin bar of an adjacent rim and prevents an a rasion of the same.

We claim:

1. A case or cabinet section having spaced walls of metal with intervening heat resisting materiahand means for connecting the rim portions of the walls together, including an insulatin bar and a plurality of separate .connectlons between the bar and each wall, the several connections being spaced from the other wall and from each other.
